Operator Station Enhance your comfort, operation, and visibility. The 320D GC Series 2 allows you to focus on your job. 4
Operator Station The ergonomically designed operator station is spacious, quiet, and comfortable, assuring high productivity during a long work day. All switches are located on the right-hand console for convenient access. Monitor The monitor is a full-color Liquid Crystal Display (LCD). It has the capability of displaying information in 42 languages. Joystick Control Low-effort pilot-operated joystick controls are designed to match your natural wrist and arm position for maximum comfort and minimum fatigue. Seat The suspension seat provides a variety of adjustments to accommodate a wide range of operators. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt adjustments, to meet operator needs for comfort and productivity. Console The hand rest can be adjusted to meet individual preferences, improving operator comfort and productivity during the course of a day. Climate Control Positive filtered ventilation with a pressurized cab is standard. Fresh air or re-circulated air can be selected with a switch on the left console. Cab Exterior The cab shell features thick steel tubing along the bottom perimeter of the cab, improving resistance to fatigue and vibration. Cab Structure and Mounts The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort. Thick steel tubing along the bottom perimeter of the cab, improves resistance to fatigue and vibration. Windows To maximize visibility, all glass is affixed directly to the cab, eliminating window frames. The upper front windshield opens, closes, and stores on the roof above the operator with a one-touch action release system. Wipers Pillar-mounted wipers increase your operator s viewing area and offer continuous and intermittent modes. 5
Engine A powerful engine with excellent reliability and low fuel consumption delivering more while boosting your bottom line. The Cat C7.1 engine has been designed to meet U.S. EPA Tier 2, EU Stage II regulations, and China Tier 2 emission regulations. The engine is powerful, strong, and durable to meet all of your application needs. The C7.1 engines incorporate proven, robust components and precision manufacturing you can count on for reliable and efficient operation. This is a proven engine that boasts improved reliability, as it s less sensitive to low quality fuel and also delivers better fuel consumption. Automatic Engine Speed Control Automatic engine speed control is activated during no-load or light-load conditions which reduces engine speed to minimize fuel consumption. Air Cleaner The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when dust accumulates above a preset level. Filtration System The C7.1 engine features an improved filtration system to ensure good reliability to fuel injection system components. Intervals have been extended and the number of filters reduced to maximize your profit potential. Low Sound, Low Vibration The Cat C7.1 improves operator comfort by reducing sound and vibration. 6
Hydraulics Efficient hydraulic system with low effort joysticks provides precise control regardless of your application. Hydraulic System Hydraulic system pressure is 35 000 kpa (5,076 psi) with 392 L/min (103.6 gal/min) flow from each of the two hydraulic pumps for increased digging performance and productivity. Pilot System An independent pilot pump enables smooth precise control for the front linkage, swing, and travel operations. Component Layout The 320D GC Series 2 hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves, and hydraulic tank are located close together to allow for shorter tubes and lines between components, which reduce friction loss and pressure drops. Boom and Stick Regeneration Circuits Boom and stick regeneration circuits save energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs, and increased fuel efficiency. Hydraulic Cylinder Snubbers Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life. Hydraulic Activation Control Lever With the hydraulic activation lever in the neutral position all front linkage, swing, and travel functions are isolated. Hydraulic Cross-Sensing System The hydraulic cross-sensing system utilizes each of two hydraulic pumps to 100 percent of engine power under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns. 7
Undercarriage and Structures Strong and durable, all you expect from Cat excavators. Carbody Design and Track Roller Frames The X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life. Main Frame The rugged main frame is extremely durable and designed for the toughest applications. Undercarriage Durable Cat undercarriage absorbs stresses and provides excellent stability. Rollers and Idlers Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life to keep your machine in the field and working longer. Standard Undercarriage The standard undercarriage is well suited for applications that require frequent repositioning of the machine, restricted work space, or uneven rocky terrain. 8
Front Linkage Reliable and durable to meet all your application needs. Cat front linkages are designed for maximum versatility, productivity, and high efficiency whatever the application. Boom and Stick The 320D GC Series 2 is offered with a reach boom 5.7 m (18'8") and one standard stick 2.9 m (9'6") configuration which covers all the utility applications. The 2.9 m (9'6") stick is the most versatile option and a very good fit for truck loading and trenching applications where you need additional working range. Bucket Efficient for your work. Buckets Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency. Utility Buckets (UD) These buckets are for digging in low-impact, low-abrasive material such as dirt, loam, and clay. 9
Service and Maintenance Simplified service and maintenance features save you time and money. Ground-Level Service The design and layout of the 320D GC Series 2 was made with the service technician in mind. Most service locations are easily accessible at ground level to allow service and maintenance to get completed quickly and efficiently. Air Filter Compartment The air filter features a double-element construction for superior cleaning efficiency. When the air filter plugs, a warning is displayed on the cab monitor. Maintenance free batteries are standard along with a battery disconnect switch. Pump Compartment A service door on the right side of the upper structure allows ground-level access to the hydraulic pumps, hydraulic filters, engine oil filter, and fuel filters. Radiator Compartment The left rear service door allows easy access to the engine radiator, hydraulic oil cooler, air-to-air aftercooler, and AC condenser. A reserve tank and drain cock are attached to the radiator for ground level maintenance. Greasing Points A concentrated remote greasing block on the boom allows the greasing of hard-to-reach locations on the boom and stick. Fan Guard The engine radiator fan is enclosed by a steel guard that provides protection when carrying out routine service and maintenance. Anti-Skid Plate Anti-skid plating covers the entire upper structure and storage box to prevent slipping during maintenance. Safety is further enhanced with the addition of countersunk bolts to reduce trip hazards. Diagnostics and Monitoring The 320D GC Series 2 is equipped with Scheduled Oil Sampling (S O S SM ) ports for the hydraulic system, engine oil, and coolant. Standard hydraulic test ports enable a service technician to quickly and easily fault find in the event of service issue. 10
